a lot of fuel systems in cars have Schrader valves up top so that you can hook up a pressure gauge when troubleshooting.

if they can keep 90psi of hot gasoline contained to a level that the NTSB is happy, they're fine for your bike tire.

the presta valve is thinner which is better for thin bike tires i think?

i guess if you wanted to be super autistic about it, you could argue that the mass of a schrader stem is larger and so theres more wheel unbalancing effect. But no, 70% of presta usage is to be able to sniff and say, oh, no, I need to get my adapter out to refill with this proletariat air station at the shell

i was more going by

quote:

The outer valve stem is manufactured in various lengths for different applications, and has a narrower diameter (6 mm) than Dunlop and Schrader valves (8 mm). The weakest point of a bicycle rim is usually the hole for the valve stem. The smaller hole for a Presta valve makes it possible to have extremely narrow wheels while maintaining sufficient strength in the wheel.
